What create_dither does on tdmcp — TouchDesigner MCP server
AI agents use create_dither to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.
Why create_dither is rated Medium
This tool creates new visual effects and components within a TouchDesigner project. While it modifies the project state by adding new elements, these changes are reversible (components can be deleted or modified), making it a Write operation rather than Destructive.
From the tool's definition The tool description states it 'Creates a new baseCOMP under' [truncated], indicating it creates/instantiates new visual components in a TouchDesigner project. The verb 'Build' and 'Creates' confirm generative intent.
Attacks that exploit this kind of access
The rule that runs create_dither safely
PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_dither, this is the rule to start with:
create_dither stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect tdmcp — TouchDesigner MCP server, apply this rule, and every create_dither call is checked against it from then on.
